JACB H. BEIDLER, OF MOUNT P'ULASKI, ILLINOIS;

BRICK-KILN.

SPECIFICATION forming part of Letters Patent No. 278,080, dated May a2,1883.

Application liled February 1,A 1883. (No model.)

- To all whom it may concern:

Beit known that I, JACOB H. BEIDLEma citizen of the United States,residing at Mount Pulaski, in the county of Logan and State of Illinois,have invented certain new and useful Improvements in `Brick-Kilns,` ofwhich the following is a specification, reference being had therein tothe accompanying drawings.4

This invention relatesto certain new and useful improvements inbrick-kilns, and has for its objects to provide, rst, for introducing tothe tire-arches atmosphericair in regulated quantities, whereby theproper amount of oxygen may be supplied in order to effect a thoroughand perfect combustion of the fuel secondly, to provide for maintainingan equal amount ofheat throughouttheentirekiln and, thirdly, insupplying combustible material or fuel to the load 77'or mass of brickbeing burned. These objects are accomplished by thc means illustrated,the same consisting of forin-` ing the bed or foundation for the kiln ofclay or cement, and in building up in the same a number oflongitudinaland transverse air passages or conduits communicating with each otherand with the lire-arches, and supplied with suitable devices forregulating the influx,

and the direction of the air. It further consists of a suitable crate orcage constructed of incombustible or lire-proof material and adapted tocontain a quantity of coal and to' be placed at any convenient point ofthe kiln, the load being built up around it. l y

In'the accompanying drawings, forming a part of this specification, andon which like letters of reference indicate corresponding features,Figure 1 represents a longitudinal vertical section of my improved kiln;Fig. 2, a transverse vertical sectional view of the same. In thedrawings, the letter A indicates the basisor foundation of my improvedkiln, the same being constructed of clay or cement, and the letter Bindicates a series of longitudinal conduits or air-passages constructedot' tubular tiles placed in the body of the base. Running transverselythrough the foundation A of the kiln is a series of air-conduits, G,formed of the same material and constructed in the same manner as thatabove described. This series of conduits is located below thelevel orplane of the bed of the kiln, and is so situated adapted to tit snugly'within the conduits, and

provided at any suitable point with acrossrod, g, the latter serving toengage with a suitable rod, H, by means of which the said valve is movedalong the conduit in such manner as to entirely or partially close thecommunication between the longitudinal and transverse conduits, theobject of which is also to provide for regulating the influx of air.

The letter I indicates the walls of the kiln, the same being oftheordinary or any approved construction and built upon the foundationA, the latter being properly leveled off at a suitable distance belowits surface for this purpose. Within these walls is built or arrangedthe load of bricks to be burned, the same being placed within the kilnin the ordinary manner.

In some instances, as will hereinafter appear, it is desirable toprovide the kiln with fuel at one or .more points in the load, and forthis purpose I construct a cage or crate, preferably of iron, in theform of grating or cross bars, within which is placed a quantity offuel. The tire-arches are provided with doors L, by which they may bepartiallyor wholly closed, according as circumstances may require.

I have ascertained that when the wind is blowing somewhat high the kilnon that side opposite to the point of the compass from which the wind iscoming becomes relatively cooler than the diametrical side of the kiln.This frequently results in producing an inferior quality of brick, asthose which occupy the portion of the kiln which becomes cooled by thewind, as above stated, do not receive sufficient burning, while-those onthe opposite side are apt to be overburned. To prevent this difliculty Ihave arranged conduits in such a manner that, no matter in "whatdirection the wind is blowing, an increased amount of draft may besupplied tothe fire-arches, and agreater degree of heat maintained forthe purpose of making the fire hottest near the side ofthe kiln which issub- Q eeaoso jected to the cooling action of thewind. The slidingvalves G are arranged so as to cut oi' the draft and direct it to thedesired end of the fire-arches.

In some sections of the country the wind is known to blow from one pointfor aconsiderable length of time, and when this is the case the kilnbeing loaded has placed Within the load one or more of the fuel-cratesK. This fuel becomes ignited by reason ot' the accumulated heat, and theblaze penetrates the mass when the bricks have become somewhatcontracted, and thus serves to keep up the additional amount of heatrequired to counteract the cooling effects oi' the wind, this latterdevice being used only in extreme cases when the valve mechanism andconduits above alluded to are insufficient for this purpose.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In abrick-kiln, the foundation,constructed of clay or cement andprovided with firearches having suitable doors, and a series oflongitudinal and transverse conduits arranged at right angles with eachother and communieating with the fire-arches, in combination withsuitable valves whereby the draft may be *wholly or partially cut off atone or more sides, so that the air maybe fed from any quarter ot thecompass, substantially as and for the pur-v pose specified.

2. In a brick-kiln, the combinationof the foundation, provided withtire-arches, and the series of air-conduits and regulating-valves withthe removable fuel-crates, substantially as shown and described.

3. The combination. with a brick-kiln, of one or more removablefuel-crates adapted t0 be placed in the load or between the bricks beingburned, whereby additional fuel and its resulting heat are supplied, asand in the manner set forth.

In testimony whereof Iafxmy signature in presence of two witnesses.

JACOB H. BEIDLER.
